WRAPPING-MACHINE.

Specification of Letters Patent.

To all whom it may concern.

Be it known that I, CUR'r I{UENTZVEL, a subject of William II, Emperor of Germany, residing at Akron, in the county of Summit and State-of Ohio, have invented new and useful Improvements in Wrapping- Maohines, of which the following is a specification.

This invention relates to improvements in devices for wrapping a continuous strip of material about an annular member so that the wrapping is applied in a plane at right angles to the plane of the revolution of the object;

The general, object of the invention is to wrap a strip of material about anobject,

such for instance, as a coil of wire or for wrapping a strip of paper about a finished tire, of course, the tire or corein either instance being an annular ob ect. Provision is; made for continuously wrapping about an annular object a continuously-fed strip of material and the mechanism by which this objectis accomplished forms an essential feature ofthis invention, the invention embodying a horizontal rotatable shuttle with an open gape revolving about an annular object mounted in a vertical position inorder to effect orcarry out the winding operation. I

With the foregoing and other objects in view, the invention consists in the novel constructlon, combmatlon and arrangement of parts constituting the invention to be heremafter specifically described and illustrated in the accompanyingdrawings which form apart hereof wherein is shown the preferred embodiment of theinvention, but it is to be understood that changes,variations and modifications can be resorted-to which I come within the scope of the matter herein- 'from'the right of Fig. 2; and Fig 4, is a plan View vof a shuttleemployed. I

The mechanism embodled in' this machine consists of an L shaped frame, one member 1 of which is usually arranged at right angles to the other member 2, the latter em .left in. Fig. 2, it will mainta Patented Oct. 13, 1914. Application filed August 6, 1913. Serial 180,783,431,

purpose to be later described. The frame 2 is preferably fashioned in the form of a parallelogram and is also provided with a transversely-extending pin 6 forming a pivot for an osclllating arm 7 the lower end of which is provided with a pin 8 on which is mounted a roller 9 provided with a concave face. The member 2 is also provided with a bearing 10 (see Fig.3) the opening in which is arranged in the same horizontal plane as the axis of the pin 6. The member 1 is also provided with a bearing 11 provided with an opening in. horizontal alinement with the opening in the member 10. and in these two openings as bearings is mounted a transversely-extending shaft 12, on the outer end of which is mounted the upper end 13 of an oscillating arm 14, the lower end of which is provided with ,a transversely-extending in or shaft 15, Extending between the pins 8 and 15 isa connecting bar 16 provided'with an openingin which is mounted a manually-operated pin Extending from a cross bar 18 connecting the lower portions of the posts 3 and 4 ofthe frame 2 and the upper portion of the frame 2 is an arm 18 formed in the arc of a circle and which is provided with a plurality of openings 19 adapted to receive the inner end of the pin 17 so that when the two oscillatory arms 7 and 14 are shifted they may be locked in any pro-determined position through the medium of the pin 17. By this arrangement it willbe seen-that as the connecting or cross-bar 18 i parallel-ism with the upper porti n of the frame 2 and that the two rollers 9 'and 20 will be raised in a true horizontal plane] for av purpose. to be later described. Mounted on the shaft 12 outside of the arm 14."ifs1.a"

sprocket wheel 21 and mounted on the shaft 15, inside of the roller 20 is a sprocket wheel 22 and connecting'these two sprocket wheels is a sprocket chain 23' bywhich motion is conveyed from the shaft 12 to the roller 20.

The two rollers 9 and 20 having concave peripheries are designated to support some annular object, such for instance as a tire or a coil 24 and in order to shift the vertical position of-the latter the oscillatory arms and 14 are oscillated to thereby raise or lower the annular object, and when in a determined position further movement of the two arms is arrested through the medium of the pin 17 engaging in one of the aperturesv 19 of the curved arm 18.

In order to revolve the annular object supported on the rollers 9 and 20ithe following mechanism is employed z-A suitably driven shaft 25 is provided on which a bevel gear 26 is mounted, and fixedly mounted in a hearing in the shelf 5 is a vertical shaft 27 on the lower end of which is a bevel gear 28 adapted to interniesh with the bevel pinion 26. The shaft 27 bears a sleeve 32 carrying a worm 30 arranged to mesh with a wormwheel 31 on the, horizontal shaft 12, so as to induce relatively slow rotation of the lateral shaft while the rotation of the shaft 27 is comparatively rapid. Secured to the sleeve 32 is a member 33 of a clutch, and mounted on the shaft 27 is the companion and shiftable member 34 of the clutch, the latter being shafted by a link 35 which is connected with a bell-crank lever 36 operated by a link 37 connected with afoot-treadle 37', by which means clutching engagement between the members 33 and 34 is induced to thereby control the rotation of the worm-wheel 31 and the rollers 9 and 20 through the medium of the sprocket-chain 23.

The annular object 24, whatever its nature may be, is supported in its upright position through the medium of a standard 38 projecting upwardly from the frame 2 provided at its upper end with a vertically-adjustable slide 39 from which projects a horizontal arm 40 provided with a head 41 hearing a pair of inclined arms carrying rollers 42 adapted to engage the upper portions of the object 24 and hold it during its revolution.

Theframe member 2 is provided with a laterally extending curvilinearly formed horizontal bracket 43 provided at its marginal portion'with a horizontal flange 44 above which extends a polygonally-shaped porggn 45. Mounted on the upper face of the member 43 is a ring-shaped member 46 provided with apertures arranged in radial registration'with corresponding apertures in the polygonalmember 45 and in these sets of bearings are laced the axles of cone-f shaped rollers 4 arranged radially with respect to the center of the body of the annular object 24. Mounted at intervals and preferably polygonally arranged on the member 45 are pins 48 on which are mounted flanged rollers 49. The position of these rollers 49 is such that an annular object will run on the broad faces or peripheries of these rollers 49 and they are so arranged to form a combined track or running surface for a shuttle carrier, to be described. One of the rollers in the set or series of rollers just described and denominated in the drawings by the reference numeral 50, is larger than the rest and forms a terminal roller for a purpose to be later described- These rollers 49 and 50 are rotated as follows: Mounted on the upper end of the shaft 27 is a flanged pulley 51 around which runs a belt 52 which passes around the outer faces of the rollers 49 and around the face of the pulley 50 and from thence around a shuttle, (to be described), and back to the pulley 51. One of the rollers 49 and specifically 53 is pos tioned in spaced relation with-respect to the roller 50 and the opening existing between these two rollers serves as a space through which is passed an annular object 24 when set on the rollers 9 and 20.

Mountedto revolve horizontally on the conical rollers 47 is a shuttle-carrier in the form of a broken ring with its under face 70 adapted to run on the rollers and approximately L-shaped in cross-section to provide when positioned a circularly-formed seat for the shuttle. The outer portion 71 of the shuttle-carrier projects laterally to engage the peripheries of the rollers 49 and 50 and be held between the flanges of said rollers which latter serve to hold the shuttle from vertical movement and to constitute guiding means therefor. 3 4

The shuttle employed consists of a circularly-formed box 54 provided with upwardly-extending marginal walls 55 and 56. The general form of the shuttle is that of a broken annulus that is to say, an annulus Witha section removed therefrom and with the ends 57 of the annulus closed and the wall 56 interrupted at 58. In this open portion. are placed a pair of uprightpins or rollers 59 for a purpose to be described. Extending inwardly from the inner wall 56 of the shuttle is a plate 60 on which are a plurality of pins 61 around which the continuous strip of material is drawn and constitutes a tension device on the feeding mechanism of the continuous strip of material from the shuttle. The continuous 'strip of material contained in the shuttle is wound from end to end around the outer face of the inner wall 56 and at each end of said shuttle the material is bent back on itself to constitute a series of folds with the ends or creases thereof ap roximately at the ends 57 of the shuttle an these folds, designated in the drawings by the reference numeral 63, are laid u" on each other and pressed together until t e entire containing portion of the shuttle is filled, 'wlth the inner end 64 of the continuous strip of material drawn out of the shuttle throu h the openingand carried inwardly aroun the tension pins 61 and 59 to the annular object 24.

. In operation the annular object 24 is slowly rotated in a vertical lane on the rollers 9 and 20 as already d dscribed, and

during this revolution the annular Object is means of the guiding rollers 42. In ordermaterial 63 from the interior mas er guided and held in its vertical position by to wind a strip of material 63 about the annular object 24 during its revolution. the loose end 64 is, applied to the face of the annular object 52 i and as the shuttle 54: re

volves, the continuous strip of material is drawn out and applied helica-lly to the an-' 'nular object 24 in the manner shown in Fig.

2 and this operation is continued until the entire surface is covered by at least one layer of the continuousstrip of material.

The continuous withdrawal of the strip of 54 is--permitted by the fact that the various folds or layers of the strip are so arranged as to permit theirv inward withdrawal through the opening )58 in the shuttle wall and as the'strip of material is continuous,

although folded circumferentially in the shuttle body each layer is freely inwardly removablethrough the opening 58, the inner folds being withdrawn first and gradually those folds along the-outer wall'55 are later removed; w

The opening'existing between-the ends of the shuttle permits the setting of the annu-.

lar object 2i in placeand when the shuttle revolves, it revolves about the center of the body portion of the annular object 24.
